摘要:
在六次甲基四胺存在下,通过水热法分别在水、乙醇和乙二醇反应介质中制备了菊花状、银莲花状和花椰菜状三种不同形貌的氧化铜纳米结构.利用X射线衍射(XRD)和扫描电子显微镜(SEM)对产物的物相及形貌进行了表征.结果表明,反应介质的极性和反应温度对氧化铜的形貌有一定影响.用热分析法考察了不同形貌的纳米CuO对高氯酸铵热分解的催化作用.

Abstract:
Three kinds of CuO nanomorphologies with chrysanthemum-like, anemone-like and cauliflower-like structure have been prepared by a hydrothermal method in presence of hexamethylenetetramine (HMTA) in water, ethanol, and glycol solution, respectively. The phases and morphologies of the as-prepared products were characterized by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The polarity of the reaction medium and reaction temperature have the effect on the morphology of CuO. The catalysises of CuO with the different morphologies for ammonium perchlorate (AP) decomposition were investigated by thermal analysis.
